[Mitral valve prolapse: a benign abnormality?].

Abstract

Mitral valve prolapse should be considered a benign condition as there are few complications. The natural history is not significantly different to that of a matched control population. There are potentially severe forms of the condition which are mainly observed in specialised centres and this introduces a bias in patient selection when compared with the general population. These forms are relatively rare in clinical practice and can be easily identified by simple echocardiographic criteria of valvular thickness. In any case, patients with mitral valve prolapse should be reassured in order not to create or unduly increase anxiety which in itself may cause incapacity.
